slowdown at startup

My computer takes several minutes to boot up now.
The problem may have started when J.River
media jukebox was installed. Unfortunately, I did
not do a system restore.
Could some of the entries in the follwoing
hijackthis log be the culprit? Advice appreciated.

Re your question:
At startup, applications like spampal, edexter winpatrol, load fast and then the slowdown
occurs: the yellow (orange?) disk access light
stays on for nearly a minute. At first, I thought
it might be a Norton problem but re-installing
liveupdate did not change anything.
Which entries could I safely delete from my
hijackthis log to re-check? Thanks.
